I’m sorry but I really have no idea I wish I could help
2(2ax-y)=3ax-4y
4ax-2y=3ax-4y
Move 3ax from the right to the left. You do so by subtracting 3ax from both sides. Once doing so, you should have:
ax-2y=-4y
Isolate ax. You do so by adding (-2y) to both sides. After doing so, you should have:
ax=-2y
To isolate y by itself, you divide everything by -2, thus, equaling y= ax/-2
A. (18,29)
B. 3x + 4y = 170
C. 50 feet
D. Y=5; 100sec
Answer:
y = - 15.57x² + 179.32x + 0.20
510
Step-by-step explanation:
The quadratic model obtained using a quadratic regression solver with Coefficient rounded to the nearest hundredth is :
y = - 15.57x² + 179.32x + 0.20
Where, height = y
x = time
Using the model obtained ; the height, to the nearest foot, at a time, x = 6.4 seconds.
y = - 15.57x² + 179.32x + 0.20
y = - 15.57(6.4^2) + 179.32(6.4) + 0.20
y = 510.1008
y = 510
